SPRAY NozZLE Filed Sepr/` 24, 1934 Gnorueg :Srweritor Patented lSept. 10, 1935 UNITED STATES PATENT OFFICE 7 Claims.

My invention relates to spray nozzles, and particularly relates to a controldevice vand nozzle construction operating to control the diffusion of the spray. The primary object of the invention is to provide a nozzle which -may be regulated to diffuse the spray either proximate the nozzle or at a distance therefrom, whereby the lower branches as well as the upper branches of trees may be sprayed with equal results.

Another object of my invention is to provide a nozzle having an improved valve structure which is operable to provide distant or proximate diffusion-of spray, or is operable to entirely shut off or close the flow of spray fluid.

Another object of the invention is to provide improvements in spray nozzle heads and the apparatus contained therein operating to diffuse' the spray fluids.

In the drawing my invention is shown in its entirety and indicated by the Figure 1. It consists of an elongated barrel 2 provided with a three-way fitting 3 at the inlet end. Fitting 3 has a fluid inlet 3 and a control portion 3" the latter being in line with the axis of the barrel, while the former is diagonal thereto. The portion 3 is provided with female threads 4 into which are threaded the male threads 5 of the shaft or control rod 6, while a retaining cap -I is secured to the end of the fitting. A handle 8 on the end of the rod exterior to the barrel provides a means for rotating rod 6. Rotation of the rod in one direction or the other will move it back or forth within the barrel. The fitting 3 is affixed to the rearward end of the barrel.

The forward end of the barrel has an enlargement or transversely enlarged portion 9 thus providing an internal ledge or seat I interiorly of the barrel. The rod 6 projects into the interior of the enlarged portion 9 where it terminatcs in a head II. Mounted upon the rod 6 is a sleeve I2 provided with a forward flange I2 and a rearward flange I2" which are spaced somewhat from one another. Sleeve I2 is mainf spraying the top-most branches of a tree.

tained upon rod 6 by the head II. Between the sleeve I2 and the ledge or seat I0 is a spring I3 coiled about rod 6. This spring bears against the sleeve I2 urging the rod .to the right or forwardly viewing Figures 2 and 3. 5

Connected to the sleeve I2 by means of the down-turned lugs I4 of its fingers I4 is a diffusing member I4. This member has a central aperture I in line with the axis of rod 6. The member I4 extends about the head II, in outl0 line being somewhat cylindrical in shape. Extending through the sleeve I2 are a number of passageways I2a. Fitted to the end of the enlarged portion 9, by suitable threads, is a retaining member I5 which is provided with a sub- 15 stantial aperture I5 in its end I5.

Between the end I5 and the end of the enlarged portion 9 of the barrel are placed two disks I6 and I'I. The innermost disk is formed of somewhat yieldable material and serves as a gasket and a seat for the end of the member I4 when pressed against it, and is provided with a central aperture I6. The outer disk II is a discharge disk and is provided with a discharge aperture I'I'. By providing disks II having dif- 25 ferent size discharge openings the size of the discharge opening of the nozzle may be lvaried by changing the disks I'I. 'l

In operation, the member 3' is connected to a fluid supply, which may be a spray pump. The spray fluid passes into barrel 2 and toward the enlarged end thereof, passes through openings I2a, about the spring I3 and the member I4 to pass out the nozzlethrough openings I'I. This is the operation viewing Figure 2. The fluid so discharged does not immediately pass into spray form but travels some distance before doing so. When head II and member I4 are in the position shown in Figure 2 the nozzle may be used for Figure 3 shows the nozzle arranged for spray-.Iv ing the lower branches of a tree. In this view the head II is moved forwardly by threading rod 6 in the threads in the member 3, this allows the member I4 to be moved to the position where 45 it is pressed against I'I shutting out all flow of fluid except through the aperture I5. The member I4 is moved forwardly by the expansion of spring I3 which bears against and moves the sleeveI2, the sleeve carrying the member I4. In this position together with the smallness of aperture I5, the proximity of the head II, and the fluid pressure, the fluid discharged from the apertures I5 and I1' forms a fine spray, this it does as it passes from the nozzle. In passing in Figure 2 the fluid passes from both sides ofthe member Il as shown by the arrows. However, in Figure 3 the fluid discharged must pass through the aperture l5, and this aperture being comparatively small, together with the proximity of the head l l causes thc discharged fluid to change into a spray immediately.

The ilow of fluid from the nozzle may be entirely shutf ofi by moving the head forward to the member ii until the member il engages it, thus covering the opening I5. The 'memberl may be made of some compressible material for this purpose, such as rubber, likewise the mem,- ber I6 may be of the same material. It is to be understood that the rod 0 and head Il move somewhat independently of the sleeve I2. However when the head is moved backwardly a sumcient distance it engages the sleeve I2 and moves it also, together with the member I4 which travels with the sleeve.

While a specific form of the improvement has been described and illustrated herein, it is desired to be understood that the same may be varied, within the scope of the appended claims,

without departing from the spirit of the in,

vention.

Having described my invention, I claim- 1. A spray nozzle including a barrel having an enlarged discharge end providing an interior seat, a control rod movable back and forth therein terminating in a head, asleeve on the rod rear` wardly of the head, a spring seating between the sleeve and the seat and urging the sleeve forwardly, a diffusing member provided with a discharge opening carried by the sleeve, a disk provided with a discharge opening terminating the barrel, the rod when moved forwardly releasing and permitting the spring to cause the diffusing member to cover the disk whereby the relative size of its discharge opening produces a spray proximate the end of the nozzle, and when the rod is moved rearwardly compelling the diffusing member to uncover the disk whereby the relative larger size of the aperture in the disk causes the spray to form at a distance from the nozzle.

2. A spray nozzle including a barrel having a discharge end provided with an interior seat, a control rod movable back and forth therein terminating in a head, a sleeve on the rod rearwardly of the head, a member located between sleeve and seat and urging the sleeve forwardly, a diusing member provided with a discharge opening carried by the sleeve, a disk provided with a discharge opening terminating the barrel, the rod when moved forwardly releasing and permitting the urging member to cause the diffusing member to cover the disk whereby the relative size of its discharge opening produces a spray proximate the end of the nozzle, and when the rod is moved rearwardly compelling the diffusing member to uncover the disk whereby the relative larger size of the aperture in the disk 5 causes the spray to form at a distance from the nozzle.

3. The invention as claimed in claim 1 including construction for moving the head to a position to obstruct and stop the flow of fluid from l0 the discharge opening of the nozzle.

4. A spray nozzle including a barrel ha"ing a discharge end provided with an interior seat, a control rod movable back and forth within the barrel and terminating in a head in the disl5 charge end thereof, a sleewe on the rod rearwardly of the head, a spring seating betveenthesleeve and seat and urging the sleeve forwardly, a dif- Y fusing member provided with rearwardly directed arms attached to the sleeve and provided 20 with a discharge opening in line with the axis of the head and rod, a disk provided with a discharge openingfterminating the discharge end of the barrel, the rod when moved forwardly releasing and permitting the spring to cause the 25 diiusing member to cover the disk whereby the relative size of its discharge opening produces a spray proximate the end of the nozzle, and when the rod is moved rearwardly compelling the diffusing member to uncover the disk whereby the 30 relative larger size of the aperture in the disk permits the spray to form at a distance from the nozzle.

5. A spray nozzle including a barrel having a discharge end provided with a discharge aperture, 30 a` diffusing member provided with a discharge aperture relatively smaller than the discharge aperture of the barrel movable back and forth in the'ba'rrel, and a head located interiorly of the diffusing member and barrel and movable 40 back and forth which when moved backwardly carries the diffusingmember with it permitting fluid discharge from the nozzle to form a spray at a distance therefrom, and when moved forwardly releasing and permitting the spring to cause the diffusing member to cover the discharge opening of the nozzle whereby the fluid discharged forms a spray proximate the nozzle.
